Evaluation of Novel Lung Function Parameters in Patients With Chronic Obstructive Pulmonary Disease (COPD)

• Conditions: Obstructive Ventilation Disorder; Pulmonary Emphysema; COPD

• Registration Number: NCT02827721
• Lead Sponsor: Universitätsmedizin Mannheim

Brief Summary

Current guideline-based criteria defining COPD do not meet the challenges set by the complex pathophysiology of the disease. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of COPD.
